Classically ganglions can be related to joints or tendons in the hand. The most common involve the tips of the fingers, the bases of the fingers on the palmer surface and the both surfaces of the wrists. They contain the lubricant for tendons or joints. They are encased in a fine smooth covering. They are quite harmless although they can be unsightly and uncomfortable.
They usually occur late as a result of wear and tear or earlier secondary to a hand or wrist injury. Ganglions can be of varying size and can fluctuate. Patients complain of symptoms associated with these, which is more a reflection of the underlying injury. These can be managed conservatively if not too large, or surgically.
Ganglions are cysts which communicate with joints or tendon sheaths. They can be associated with a dull ache which is usually a reflection of the underlying injury. Surgery is an option.
